How Claude Code mods work
- A mod is a plugin with a JavaScript or TypeScript module that runs inside Claude Code (version 2.1.287 or later). It can draw panes beside the transcript, a band above the prompt, buttons and toasts, restyle the spinner and tool rows, and watch or rewrite tool calls and prompts.
- It installs like any plugin: add its marketplace with /plugin marketplace add owner/repo, then /plugin install name@marketplace.
- Check what a mod can reach before installing: it runs with your permissions. Reach goes from drawing only, to reading files, to writing files or running processes, to the network. Run claude plugin validate on a clone to list its hooks and calls without running it.
- Turn one off from the Installed tab in /plugin, or start Claude Code with --safe-mode to skip every customization for a session.

More memory & instructions mods
handoff-nudge
smhasan-yad/claude-mod-handoff-nudge
Offers /handoff-journal or /handoff-local above the prompt when the context passes 60% and 85%, or the session runs past 3 hours. Reads only the engine's own usage figures: no tokens until you click.
house-rules
Jvrd97/claude-house-rules
Turn CLAUDE.md rules into hard blocks: protected paths, no new report files, banned commands, and rules re-pinned every N prompts and after compaction.
handoff
oleksandrkodua/qa-mods
One of four animated helpers (paperclip, wizard, dog, cat; dots under it switch, the choice is kept) beside the band above the prompt on desktop, a one-line face in the terminal: calm / worried / panic by context fill, with random Ukrainian remarks; /handoff puts /active-memory:amhandoff into the input box (the hud band has its button). VS Code: a hint after the answer from 80%.
house-rules
none-ascetic/claude-mods
Quietly enforces Paddy's writing rules: no em dashes in chat, files or outbound messages, and a nudge when replies run long.
handoff
lnodonly/claude-mods
A note per project folder for the next session: /handoff writes a full one, and with /handoff auto on exit saves a quick one when work happened; the next session gives Claude the note
house-rules
RobGruhl/claude-mods
BEFORE the turn: adds a system-prompt section, attaches the local time to each prompt, and registers /house-rules
